SPECIFICATION forming part of Letters Patent No. 717,289, dated December 30, 1902.

Application filed March 19, 1902. Serial No. 98,949. (No model.)

To all whom, t Wwtg/ ooncernf Be it known that we, BENJAMIN C. SCHRO- DER, AUGUST M. SCHRODER, and JOHN M. SOHRODER, citizens of the United States, and

residents of Osmond, in the county of Pierce 'and State of Nebraska, have invented a new and Improved Tilt-Hammer, of which the following is a full, clear, and exact description.

The object of the invention is to provide a xo new and improved tilt-hammer which is simple and durable in construction, very effective in operation,and arranged to permit of readily and quickly varyingthe stroke of the hammer according to the nature of the work under l5 treatment and to allow of using the hammer in any desired position within a vessel and other places.

The invention consists of novel features and parts and combinations of the same, as

:o will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front View of the improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. l, and Figs. 3 and l are 3o front views of the lifting device in different positions.

On a suitably-constructed frame A is pivoted at B' the helve B of the hammer, the said helve carrying at its forward end a hammer- 3; head B2, adapted to engage the work held on the anvil C. A spring D is secured at one end to the helve B and at the other end to the frame A, so as to impart a powerful downward stroke to the helve B after the same has 4o been swung upward and released, as hereinafter more fully described.

On the frame A are arranged bearings E and E', in which is mounted to reciprocate in an up-and-down direction a carrier F, located adjacent to one side of the helve B, and the upper end of the said carrier is pivotally con'- nected by a'pitman'G with a crank-disk H, secured on a shaft H', journaled in suitable bearings on the frame A, the said shaft being 5o provided With fast and loose pulleys H2, connected by belt with other machinery for imparting a rotary motion to the shaft H to cause the crank-disk H thereof and the pitman G to impart a reciprocating motion to the carrier F. On the carrierF is fulcrumed at I' a wiper I, adapted to swing against the under side of the helve B at the time the latter is in a lowermost position,.(see Fig. 1,) and the heel of the said wiper is provided with a shoulder I2, adapted to be engaged by a shoulder J', formed ou the heel of a holding and trip cam J, fulcrumed at J2 on the carrier F and pressed on by a spring J3 to normally swing the cam to engage its shoulder J' with the shoulderlz. The back of the wiper I is curved and adapted to engage a frictionroller K, journaled on the lower bearing E, so that when the carrier F slides downward then the back of the Wiper I moves in contact with the said friction-roller K to cause the wiper to swing upwardly into an active positionthat is, to engage the underside of the helve B. When this takes place, the shoulder l2 is engaged by the shoulder J',so as to lock the wiper I in position, and when the carrier F moves upward then the wiper imparts an upward -swinging motion to the helve B against the tension of the spring D. The cam J isalso provided with a curved back adapted to engage a friction-roller L, held on a slide L', vertically adjustable on guide-rods L2, secured on the main frame A. Now when the carrier F moves upward to impart an upward swinging motion to the helve B, as above described, then the cam J finally moves in engagement with the friction-roller L, so as to impart a swinging motion to the said cam against the tension of its spring J3 to swing the shoulder J' out of engagement with the shoulder 12, so that the wiper is released and the helve B now immediately makes its downstroke by the action of its own weight and stress of the spring D. The slide L' is held vertically adjustable to release the helve B sooner or later, according to the work under treatment, it being understood that when the slide L' is moved downward then the cam J releases the wiper I sooner than when the slide L' is farther up, and consequently the stroke of the helve B can be varied to suit the nature of the work under treatment. In order `to move the slide L' up or down, we

IOO

pivotally connect the same by a link N with a lever O under the control of the operator and adapted to be locked to the main frame A when moved to a desired position. This locking device for the lever O may consist of a pin engaging an aperture in the lever and one of a series of apertures in the frame A, as indicated in Fig. l.

From the foregoing it will be seen that the device is Very simple and durable in construction, and by the operator adjusting the position of the slide L', carrying the frictionroller L, the stroke of the helve B can be varied for the purpose mentioned. It will also be noticed that the machine can be placed in any desired positionthat is, either vertical, angular, or horizontal-as the spring D is relied on to cause the home or return stroke of the helve B.

Having thus described our invention, we claim as new and desire to secure byLetters Patentl. A tilt-hammer, comprising a pivoted hammer, a movable carrier, a pivoted wiper on the carrier and adapted to engage the hammer-helve to move the same in one direction, a holding and tripping device on the carrier for engaging the pivoted wiper to hold it in operative position, and means `for releasing the holding and tripping device, as set forth.

2. A tilthammer, comprising a pivoted hammer, a movable carrier, a pivoted wiper on the carrier for engaging the helve of the hammer to impart movement to the same in one direction, a pivoted and spring-pressed holding and tripping cam on the carrier for engaging the wiper to hold it in operative position, and means for releasing the cam from the wiper, as set forth.

3. A tilt-hammer, comprising a pivoted hammer, a movable carrier, a pivoted wiper on the carrier for engaging the hammer-belve to move it in one direction, means for moving the Wiper into operative position, a pivoted and spring-pressed holding and tripping cam on the carrier for engaging the wiper when the latter is moved into operative position to hold the same in said position, and means for disengaging the cam from the wiper, as set forth.

4. A tilthammer, comprising a pivoted hammer, a movable carrier, a pivoted wiper on the carrier and provided with a shoulder, said wiper being adapted to engage the hammer-belve, means for moving the Wiper into operative position, a pivoted and springpressed holding and tripping cam on the carrier and provided with a shoulder for engaging the shoulder of the wiper when the latter is moved into operative position, and means for disengaging the cam from the wiper, as set forth.

5. A tilt-hammer, comprising a pivoted and spring-pressed hammer, a reciprocating carrier, a pivoted wiper on the carrier, and provided with a shoulder, said wiper having a curved back and adapted to engage the under face of the hammer-helve, means for engaging the curved back of the Wiper to swing it into operative position,a pivoted and springpressed holding and tripping cam on the carrier having a curved back and provided with a shoulder for engaging the shoulder of the wiper when the latter is movedinto operative position, and means for disengaging the cam from the wiper, as set forth.

6. The combination with a hammer, of a movable carrier, a movable member on the carrier, means for moving the said member into position for engaging the hammer when the carrier is moved in one direction, and a second movable member on the carrier for engaging the irst member when the latter is moved into operative position, as set forth.

7. The combination with a hammer, of a movable carrier, a movable member on its carrier, means for moving said member into position for engaging the hammer when the carrier is moved downward, a second movable member on the carrier for engaging the first member when the latter is moved into operative position, and means for disengaging the said second member from the first member as the carrier moves upward, as setforth.

8. The combination with a pivoted hammer, of a sliding carrier, a movable member on the carrier, means for moving said member into position for engaging the hammerhelve when the carrier moves downward, a second movable and spring-pressed member on the carrier for engaging the rst member, when the latter is moved into operative position, and adjustable means for disengaging the second member from the irst when the carrier moves upward, as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
